Similar, yes, but not related to what you claim.

As I don't know which package provides linuxboot and no such package
exists in Debian: please re-assign this bug yourself.

You claim you boot via coreboot(ACPI) and linuxboot/kexec.  But the
kernel finds a device tree, and a populated one.  But this device tree
includes EFI information, but at least incomplete EFI information.

This line means that the EFI stub did not run.  So you boot with EFI and
without EFI at the same time.

Even your initrd is located in memory that does not exist in the
provided memory map in the device tree.

And here we failed two times (first CMA, then kfence) to get any usable
memory.

I don't see where this is a problem in the kernel.  The boot loader
needs to provide memory information and fails.
